Title: Improvements in devices for reducing torsional oscillations in crank-shafts
IPC: F16F15/10
Filed: 1931-12-01
Abstract: 382,787. Flywheels. SARAZIN, R. R. R., Rue du Chateau de la Chasse, St-Prix, Seine-et-Oise, France. Dec. 1, 1931, No. 33317. Convention date, June 30. [Class 122 (i).] In a flywheel device for reducing torsional oscillations in crank shafts, movable masses 6 in a hollow drum secured to the shaft are displaced against centrifugal force by means of recesses 20 in the drum which engage rollers 26 on projecting heads forming part of the movable masses, the difference in radius between the recesses and that of the corresponding projecting heads representing the radius along which the masses are displaced. The masses are connected by links 21 to a crown 22 rotating freely on a sleeve 18 secured to the shaft. A lug 23 and cavity 24 limit the motion of the crown 22.

Title: Improvements in or relating to the drawing and bulking of synthetic filament yarns
Inventor: ROGERS PAUL
IPC: D02G1/02
Filed: 1968-07-12
Abstract: 1,274,854. False-twist crimped yarns; drawing. IMPERIAL CHEMICAL INDUSTRIES Ltd. 23 June, 1969 [12 July, 1968], No. 33365/ 68. Heading D1F. A continuous process for false-twist crimping a synthetic filament yarn comprises firstly submitting the undrawn yarn to a pre-drawing stage in which it is partially-drawn, and then feeding the partially-drawn yarn to a falsetwist crimping zone under such conditions of tension that drawing of the yarn is completed in or on heating means in the false-twist crimping zone. The yarn is preferably a polyamide yarn e.g. polyhexamethylene adipamide yarn. The ratio of the draw ratio in the crimping stage to the draw ratio in the pre-drawing stage lies in the range 0.3 to 0.8 or above 1.3. In a preferred embodiment, the undrawn yarn is partially drawn between a feed roll and a faster rotating draw roll, the draw being localised at a ceramic snubbing pin. The partially drawn yarn is fed directly from the draw roll to the false-twist crimping stage wherein the yarn is passed through or over a heater and to a rotary friction device, and the yarn is withdrawn at a greater speed than that at which it is fed to the crimper. The bulk may be developed in the yarn prior to or after being made into a fabric by means of heat treatment under conditions of controlled tension and temperature.

Title: Improvements in or relating to steel well casings and method of making the same
IPC: E21B17/00
Filed: 1935-12-02
Abstract: 470,249. Making well-casings. SMITH CORPORATION, A. O. Dec. 2, 1935, No. 33376. Convention date, Dec. 10, 1934. [Classes 83 (ii) and 83 (iv)] Varying physical structure.-In a method of making thick-walled steel well-casing for oil wells, the casing is subjected to external pressure so as to compress it to a smaller diameter and thus increase its yield point in compression and enable it to withstand greater compressive forces in deep wells. The casing is preferably compressed between semi-cylindrical dies which may extend along the whole length of a section of casing or may be shorter than the casing and effect the compression in sections. The compression is effected whilst the casing is cold and may be performed in one stage or in a series of stages. Plain 0À1 per cent to 0À5 per cent carbon steel, or any other steel, may be used, and with a 0À35 per cent to 0À45 per cent carbon steel and a reduction in circumference of about 4À75 per cent produced by the dies, the yield points in compression in the circumferential direction of the casing and in tension longitudinally of the casing are stated to be raised from 45,000 lb. per sq. inch each to 80,000 lb. per sq. inch and 60,000 lb. per sq. inch respectively, enabling the casing to be inserted in wells having a depth of about 2 miles. When the ratio of pipe diameter to wall thickness is about 30, the compressive yield point should be raised to about 60,000 lb. per sq. inch and corresponding figures for ratios of 26 and 24 are 70,000 lb. per sq. inch and 80,000 lb. per sq. inch respectively. The pipe for the casing may be made by electric flash or arc welding.

Title: Improvements relating to guanidinium salts of mercapto-sulphonic acids and the preparation thereof
Filed: 1952-12-08
Abstract: New guanidinium or substituted guanidinium salts of mercapto alkanesulphonates having the formula <FORM:0735098/IV (b)/1> are prepared by reacting an S-thiuronium alkane sulphonate <FORM:0735098/IV (b)/2> with ammonia or a primary or secondary amine, e.g. methylamine or ethanolamine, n being a number from 1 to 5.  In general, the reactants are heated together in substantially equimolar proportions, suitably at 40-65 DEG  C.  An inert solvent, preferably water, may be present.  The products may be converted into the free acids by passing an aqueous solution of the guanidinium compound through a cation-exchange resin.  The S-thiuronium compounds may be prepared as described in Specification 735,070. In an example, beta-S-thiuronium ethane sulphonate is heated with aqueous ammonia yielding guanidinium beta-mercaptoethane sulphonate.

[Also in Group XXIX] Release of compressed gas prematurely discharged from a life-jacket inflating cylinder 51, Fig. 3, by inadvertant opening of closure means, e.g. a pierceable disc 52, is effected through a cylindrical bore 61 in which slides a piston 62 normally held against a spring 63 by a cable-withdrawn pin 65 in such a position that a piston bore 66 registers with an atmospheric exhaust port 67 but when the pin is removed 114 registers with a port 68 axially spaced from port 67 and connected to the life jacket (not shown). The disc piercing pin 53 is carried at the lower end of a downwardly spring-biased sleeve held by balls 56 pushed into sleeve ports by a spindle 55 having at its upper end a disc subjected to upward displacement when water gains access to a sponge 57 resulting in expansion of the same and consequent release of the balls 56 and downward movement of the pin 53 under the action of spring 54. The balls 56 may be released manually by pulling an end cover 58. In a modification the closure means comprise a nylon valve 3, Fig. 1, which is normally unseated by a rod 6. When a bell crank 10, Fig. 2, thereof is lifted by a spring-biased rod 11 on solution of a retaining plug 16; a safety pin 22 having previously been removed to allow gas pressure to lift a piston 21 to a position whereby an annular groove 28 and longitudinal passage 27 register with an outlet connection 20.
